Nor will TrackBite alone get you there without heating the tires and doing the burnout. Both are required with a car producing 1000 horsepower or more. > A properly prepped drag strip has maximum traction without any tires > rolling on it. > There are several reasons that dragsters smoke their tires: > 1) It heats the tire compound, and make it adhere to the prepped track > surface. > The ideal is when the track and tire are both at the optimum temperature. The tires must be heated past the optimum traction point so that they cool to the optimum temperate at launch. But excessive heating is bad as well. There is a huge variety of tire compounds available and a lot depends on the specific tire compound used. You can pick up barely used drag racing slicks cheap because that compound didn't work for their car.Unfortunately, it takes a bunch of trial and error to find the right compound. > 2) It removes a thin layer of aged hard rubber, and reveals fresh soft > sticky rubber. > If it removes a layer of rubber wouldn't that also remove the TrackBite? > I should note that there are other tricks that drag racers use to help get > traction.

Both too much downward force and too little downward force are detrimental. -------------- next part -------------- An HTML attachment was scrubbed...
